Epilepsy is a neurological condition that causes unprovoked, recurrent seizures. A seizure is a sudden rush of abnormal electrical activity in your brain. If a person has 2 or more seizures without other identifiable causes, they will be diagnosed with epilepsy. Epilepsy may develop in anyone, male or female, of all races, ethnic backgrounds, and ages. Some people will stare blankly for a few seconds during a seizure, while others repeatedly twitch their arms and legs. Although most patients can control their seizures with medication or surgery, for some it requires lifelong treatments to control seizures.
Epilepsy symptoms
Depending on the type of seizure, symptoms vary for patients, although a person with epilepsy will tend to have the same type of seizure each time. Seizure signs and symptoms may include:
Temporary confusion
A staring spell
Stiff muscles
Uncontrollable jerking movements of the arms and legs
Loss of consciousness or awareness
Psychological symptoms such as fear, anxiety, or deja vu
What are the symptoms of epilepsy?
Seizures are the main symptom of epilepsy. Seizures are generally classified as either focal or generalized, based on how and where the abnormal brain activity begins.
Focal (partial) seizures
alterations to a sense of taste, smell, sight, hearing, or touch
dizziness
tingling and twitching of limbs
staring blankly
unresponsiveness
performing repetitive movements
Generalized seizures
Absence seizures: These tend to cause a short loss of awareness, and a blank stare, and may cause repetitive movements like lip smacking or blinking.
Tonic seizures: Causes sudden stiffness in the muscles in your legs, arms, or trunk.
Atonic seizures: Leading to loss of muscle control, a sudden loss of muscle strength can make you fall suddenly.
Clonic seizures: Characterized by repeated, jerky muscle movements of the face, neck, and arms.
Myoclonic seizures: Causing spontaneous quick twitching of the arms and legs. Sometimes these seizures cluster together.
Tonic-clonic seizures: Symptoms include stiffening of the body, shaking, loss of bladder or bowel control, biting of the tongue, and loss of consciousness.
Following a seizure, you may not remember having one, or you might feel slightly ill for a few hours.
Treatments for epilepsy
Epilepsy treatments may help patients have fewer or no seizures anymore. Even though for some, treatment is a lifelong commitment, patients might be able to stop treatment if their seizures disappear over time. These treatments include:
Anti-epileptic drugs, which are the main treatment
Surgery to remove a small part of the brain that's causing the seizures
A procedure to put a small electrical device inside the body that can help control seizures
A special diet (ketogenic diet) that can help control seizures
How is epilepsy diagnosed?
Patients must visit the doctor if they suspect they have had a seizure. A seizure can be a symptom of a serious medical issue. To diagnose epilepsy, other conditions which cause seizures should be ruled out.
An electroencephalogram (EEG) is the most common test used to diagnose epilepsy. This test involves placing electrodes on your scalp to search for abnormal patterns in your brain’s electrical activity. Your doctor may ask you to perform a specific task during the test or it may be performed while you sleep.
Epilepsy causes
In half of the people with epilepsy, the condition has no identifiable cause, while in the other half the condition could be traced to various factors, including:
Genetic influence: Some types of epilepsy, which are categorized by the type of seizure you experience or the part of the brain that is affected, run in families.
Head trauma: Head trauma as a result of a car accident or other traumatic injury can cause epilepsy.
Brain abnormalities: Abnormalities in the brain, including brain tumors or vascular malformations such as arteriovenous malformations (AVMs) and cavernous malformations, can cause epilepsy. Stroke is a leading cause of epilepsy in adults older than age 35.
Infections: Meningitis, HIV, viral encephalitis, and some parasitic infections can cause epilepsy.
Prenatal injury: Before birth, babies are sensitive to brain damage that could be caused by several factors, such as an infection in the mother, poor nutrition, or oxygen deficiencies. This brain damage can result in epilepsy or cerebral palsy.
Developmental disorders: Epilepsy can sometimes be associated with developmental disorders, such as autism.
What triggers an epileptic seizure?
Some people identify things or situations that trigger their seizures. A few of the most common known triggers are:
Lack of sleep
Illness or fever
Stress
Bright lights, flashing lights, or patterns
Caffeine, alcohol or alcohol withdrawal, medications, or illegal drugs
Skipping meals, overeating, or specific food ingredients
Very low blood sugar
Head injury
Although it isn’t always easy to identify triggers, since it’s often a combination of factors that triggers a seizure.
Conclusion
Epilepsy is a neurological disorder with a spectrum of potential causes, each unique to the individual's condition. While for many, the exact cause remains unknown, research has identified genetic factors, brain trauma, autoimmune disorders, metabolic issues, and infectious diseases as possible contributors. The complexity of epilepsy's etiology reflects the intricate nature of the brain's functioning and underscores the importance of personalized medical approaches. As understanding of the disorder deepens, it paves the way for more precise diagnostics and targeted treatments, offering hope for better management and improved quality of life for those affected by epilepsy.
